Automatically hide and show the dock is greyed out, how to reactivate the option?
I have been using macOS Catalina since its release but today the Dock suddenly refuses to hide. In the preference pane, the Automatically hide and show the Dock option is greyed out.
I have tried killall Dock which hides the dock for 1 second, then it comes back.
macOS details OSX Catalina 10.15.5 (19F101) Mac book pro 16" 2019
I have run into a solution, thanks to idownloadblog
just put the code below into terminal
defaults write com.apple.dock autohide -bool true
It overrides the setting in preference
